A touch display device includes a substrate, a display layer disposed on the substrate, an insulating layer disposed on the display layer, and a touch electrode layer directly contacting the insulating layer. The display layer includes a first region, a second region, and a third region. The second region is located between the first region and the third region. The second region is foldable. The touch electrode layer includes a mesh structure, wherein the insulating layer is disposed between the display layer and the mesh structure. The insulating layer includes a first layer, a second layer, and a third layer. The second layer is disposed between the first layer and the third layer. The first layer and the third layer are formed of inorganic insulating materials. The second layer is formed of organic insulating material. The thickness of the first layer is greater than the thickness of the third layer.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The touch display device as claimed in claim 1, further comprising a polarizer and a cover layer, wherein the polarizer is disposed between the touch electrode layer and the cover layer.
3. The touch display device as claimed in claim 1, further comprising a supporting film and a thin film transistor layer, wherein the substrate is disposed between the supporting film and the thin film transistor layer.
4. The touch display device as claimed in claim 1, wherein the mesh structure is overlapped with the barrier portion.
5. The touch display device as claimed in claim 1, wherein the first layer directly contacts the second layer and the second layer directly contacts the third layer.
6. The touch display device as claimed in claim 1, wherein the substrate is a continuous structure.
7. The touch display device as claimed in claim 1, wherein the second layer has at least one tapered surface close to a border of the second region.
8. The touch display device as claimed in claim 1, wherein the mesh structure has a curve edge.
